Mean Well Ent. Co. Ltd. has introduced the new SDR-75 series (75W) to make its high-efficiency slim DIN rail power product offering more complete. Now, wattages of 75W, 120W, 240W, 480W and 960W are available. The slim design of 32mm in width helps save the precious space on the rail and also makes it 41% smaller in size compare to its predecessor model DR-75. Meanwhile, SDR-75 also possesses 9 to 12.5% higher efficiency than corresponding models and the working temperature ranging from -30â„ƒ to +70â„ƒ is superior to the range of -10 to +60â„ƒ of DR-75, which response to the trend of green power with energy saving concept.
With up-to-date high performance circuit design, SDR-75 series feature with full range ac input (88-264Vac) and possess up to 90% of high efficiency, so they can be cooled by free air convection from -30Â°C to +55Â°C or +60Â°C ambient temperature under full load condition, and even up to +70oC by suitable derating. SDR-75 has 150% peak load capability and equips with overload protection of constant current limiting and delay shut down, which suits to all kinds of critical loading status, such as inductive and capacity loads.
Other standard functions include front panel LED indicator, front panel dc voltage adjustment, as well as protections for short-circuit, overload (constant current mode), over voltage, and over temperature. In addition, they comply with UL, CUL, CB, TUV, and CE certificates and also meet the EMC requirements of heavy industrial immunity level (EN61000-6-2). Suitable applications include industrial control system, semi-conductor fabrication equipment, factory automation, electro-mechanical applications, and any installations with fan-less or low noise requirements. These power supplies come with a 3-year warranty.
